On adding to this a further sublevel, i.e., "ARpd_2561602/Questions/Answered/Corrected", or "ARpd_2561602/Questions/Answered/Reviewed", for certain tags what is displayed is no longer the entire chain, but only the lowest tag. This, however, not for all tags, i.e., ARpd_2561602/Questions/Answered/Reviewed is displayed as simply "Reviewed", whileARpd_2561602/Questions/Answered/Corrected is displayed as ARpd_2561602/Questions/Answered/Corrected (i.e., correctly)

Further: if I copy one of the notes with this tag chain, and change the chain in the copied note (e.g., from ARpd_2561602/Questions/Answered/Reviewed to ARpd_Test/Questions/Answered/Reviewed), the tag chain in both the original note (and the other notes with the same tags), and in the new copied note display correctly. However, if I then delete the copied note, the tag chain returns to the incorrect display.

CN tries to display short tag name when possible (by "short" I mean the innermost name segment). However when 2 or more tags have same short name, CN displays full name to disambiguate.In your case, most probably "Corrected" is also part of some other tag's name (maybe from other section), but "Reviewed" is unique.
